BAND-CUTTER AND FEEDER FOR THRASHINGuiVl/CHINES.

GPECEFICATION forming part of Letters Patent No. 309,074, dated December9, 1884.

Application lerl June 18, i854.

` To all whom, it may concern:

Be it known that we, J osnrn AMARSHALL and FLAvrUs H. MAnsHALL, citizensof the United States, residing at Darlington, in the county ofMontgomery and State of Indiana, have invented certain new and usefulImprovements in Band-Cutters and Feeders for Thrashing-Machincs, and wedo declare the following to be a full, clear, and exact description oftheinvention,such as will enable others skilled in the art to which-itappertains to make and use the same, reference being had tothe`aecompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a side view of our device. Fig. 2 is a planview of the same, and Fig. 3 is a detail view.

This invention is an improvement on the patent grantedto us on the 29thday of Jaa' nary, 1884, and numbered 292,667; and it relatesparticularly to an improved form of feeding device in place of that usedin the abovementioned patent.

The invention consists, essentially, in constructing the feedingmechanism for the thrasher in the following manner: A proper number ofboards having upright serrated edges are attached to a rod by the endthat adjoins the carrier in such manner as to haveV a longitudinalreciprocating movement. The said rod connects two brackets hinged to theearrier, and lies below the level of the carrierapron. The ends of theboards adjoining the thrasher are reciprocated and vertically vibratedby means of eccentrics fixed on a transverse shaft, which is driven by apulley on one of its ends and a belt connecting the same with a pulleyat any proper point on the thrashing-machine. Each eccentric is set onthe ,shaft in an opposite direction from those adjoining; consequentlyany two adjacent boards will both vibrate and reciprocate alternately,by the former motion shaking and loosening the cut bundles, and, by thelatter, in consequence of the serratededgcs, carrying the same towardthe thrasher.

In the accompanying drawings, A represents the front or receiving end ofa thrashing-machine, of which a is the cylinder-shaft, carrying thecylinder a', and having on either end a driving-pulley, c2, the oppositeend being (No model.)

l provided with a pulley, a, to actuate by means of a proper belt theshaft having the eccentrics attached.

B is a chute inclined from the carrier to the thrashing-machine, one endofwhich is pivoted or hinged between the outer ends of the projectingtop sills of the thrasher-frame, below the connecting-brackets D D, andthe other end loosely attached to the front of the thrashing-machinebelow, and in proper relation to the cylinder c. The said chute isprovided with upright sides, in which is transversely journaled theeccentric shaft b, provided on one end with the pulley b, and on theother with the pulleys b2 and b3, the former of which is driven by abelt from the pulley a.

bL b4 are the eccentrics, set at equal distances apart on the shaft b,each being set in an opposite direction to the adjoining ones.

C C are the shaking-boards, each provided along its sides with theupright teeth or serrations c c, the vertical edges of which are towardthe thrasher and the inclined edges toward the carrier, the said teethincreasing in height as they approach the thrasher. The boards C G havejust sufcient space between their edges to move without binding,and eachis attached toan eccentric by a band, c', which depends from thelowersurface andits around the eccentric, the latter turning freely in it.

If desirable, cranks may be substituted for the eccentric, the cranksturning in proper openings or loops fixed to the lower surfaces of theboards; but the eccentrics are preferable. Each of the boards Chas fixedto and depending from the lower surface oi' its end nearest the carriera rectangular strap, ci, through which passes a transverse rod, d, thatconnects the lower ends of the bracketsD D. Thesaid strap is justsufliciently wide to admit the rod, but is sufficiently long to allowthe board to be reeiprocated by the rotation of its attached eccentric.

D D are the connecting-brackets, pvoted to and vertically adjustable onthe inner ends of the carrier E by means of proper pins or rods, d, andany two opposite holes, e e, the holes being in vertical series oneabove another and at equal distances apart on each side of the carrier.

e and e2 are the rollers for the carrier-apron, having bearings in theframe of the same, the

IOO

former adjacent to the brackets D, and the p latter at the'ropposite endof the frame, and es I lower ends resting on the ground when the carrieris in working position. rlhe said legs are turned up on the sides of thecarrier and the carrier is folded over the top of the thrashing-machinewhen it is necessary to move the latter. Y

e8 is a pulley on the end of the journal of the roller e2, outside ofthecarrier, and situated on the same side of the machine as the pulley b,being driven bya belt from the same. Acone of pulleys may,if dcsired,besubstituted for the pulley e, so as to give the apron-rollers a greateror less speed, the slack of the apron being taken up, when necessary, bythe sliding boX c5 and screw of. The pulleys which drive thecarrier-rollers may be arranged in either side of the machine that isdesirable.

F F are similar vertical brackets, pivoted to the top of each side ofthe carrier-frame, at opposite points on the saine, and having journaledin them the transverse shaft f.

j is a pulley on the end of said shaft, outside of the carrier, andsituated on the same side of the machine as the pulley b3, by which itis driven by means of a cross-belt.

f3 f3 are disks provided with continuous cutting-edges, which disks`fit'upon the shaft f, and haveinterposed between them the equal andsimilar washers, f 4 f 4. The said washers and disks are secured inplace by means of a collar, f5, fixed to the shaft on one side of them,and a'nut, f6, screwing tightly against them on the other side, over athreaded portion of the shaft. The ends of the shaft f are adjustable inther brackets 'FF by means of the upward-extending arms of said bracketand the horizontal set-screws f7 f7 engaging said arms.

The operation of the machine is as follows: The bundles are fed to thecarrier, which moves them at a greater orless speed (if conepulleys areused) toward the cutting-disks. After they are cut by the latter theyare thrown into the shaking-boards,vvhich spread them and deliver themupon the chute, whence they fall into the thrashing-machine.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

In a feeder for thrashing-machines, the combination of the carrier-frameE, having vertical series of adj ustment-holes e, the thrasherframebrackets D, and pins or rods d,whereby the said carrier-frame may bevertically adjusted with relation to the thrasher, substantially asspecified.

In testimony whereof we affix our signatures in presence of twowitnesses.
